To all whom t may concern.'

Be it known that I, HENRI SIMONIN, a citizen of the Republic of Switzerland, residing at Zurich, Switzerland, have invented new and useful Improvements in Machines for Rub` bing and Glazing Cloth, of which the following is a specification. c

This invention relates to fabric polishing and finishing machines in which the polishing and finishing is effected by rubbing the surface of the fabric by means of suitable tools.

It has heretofore been the practice to polish and finish fabrics by surface-rubbing from the center to the edges or at right angles to the warp. I have,however,found that this method of rubbing cannot be resorted to in polishing and finishing certain classes of fabrics for the reason that the displacement of the warp from the center toward the edges appreciably re- Ydnces the density of the fabric along its center, the difference in density being in many cases quite evident. l have discovered that this difliculty may be overcome by rubbing the fabric from the edges to the center.

The essential characteristic feature of my invention lies, therefore, in means for mov ing the rubbing-tools in contact with the fabric from its edges to its center.

A further characteristic feature of my invention lies in means for imparting to the tool-carriers a reciprocating motion from the center of and in contact with the fabric to its 'opposite edges and back to a normal or starting point out of Contact with said fabric, means being provided for clamping the edges of the fabric to its bed during the operation of the rubbing-tools.

A further characteristic feature of my invention lies in means for readily positioning the rubbing-tools to rub the fabric either from its edges to its center or from its center to its edges, according to the character of the fabric to be polished and finished.

A form of construction of the object of the invention is shown as an example in the accompanying drawings, in whichu Figure 1 is a front view; Fig. 2, a plan view; Fig. 3, an end View; Fig. 4, a section on the line A B of Fig. 1; Fig. 5, a section on the line C D of Fig. 4; Fig. 6, a section on the line E F of Fig. 4. Figs. 7 to 11 relate to details of the invention, while Figs. 12 to 14 show parts of the same in various positionsof working'.

The machine has a machine-frame which carries between standards or uprights 2, con'- nected with one another by cross-bars 1, a table-plate 3. At the front and rear of the machine, respectively, horizontal clothcar rying rollers4 and 5 are mounted on the frame of the machine.

6 and 7 are two carriages, which are guided in supports 8, vertically movable on the standards 2 in such a way that the carriages may execute a horizontal reciprocating movement on the supports in the longitudinal direction of the plate 3. These carriages have on their under sides, over the table-plate, knives 9, mounted on the carriages by means of knifeholders and directed transversely to the carriages, the two carriages 6 having the knives on their left-hand longitudinal half and the carriages 7 on their right-hand longitudinal half. The knives are displaceably mounted on the carriages and inclinedtoward the middle of the machine, so that they stand at an acute angle to the direction of the movement of the carriages. Two eccentric wheels or disks 11 are mounted on a drive-shaft 10, horizontally located under the table-plate 3 in the machine-frame, on which eccentric disks eccentric rings 12 are arranged, which are connected with the supports 8 by means of eccentric rods 13. A toothed wheel 14, driven from the drive-shaft 10, is mounted on the left-hand uprights of the machine-frame, which toothed wheel has pins 15 and 16 standing, respectively, on each side of the wheel, eccentrically to the axis of rotation of the wheel, which pins are arranged displaced at onehundred and eighty degrees to one another. With these pins pit'men 17 and 18 are con-v nected, which pitmen actuate rocking levers 19 and Q0, mounted at the foot of the left-hand standard. The rocking lever 19 engages, by means of a link 21, with the carriage 7, and

vthe rocking lever 20, by means of a link 22,

with the carriage 6, the carriages being connected with one another by cross-bars 23 and 24, respectively, so that when one carriage moves the other is also affected.

In order tov afford a soft resilient support for the cloth or fabric, an aircushion 25 is arranged on the table-plate, which cushion may be fed by an air-pipe 26 and is coated with leather straps 27 under the carriages.

28 represents clamp-plates which serve for holding fast thematerial conveyed over the air-cushion and the table-plate by clamping the edges 29 during the rubbing or treatment. (Figs. 7to 11 show front, side, and plan views and a vertical section in various positions of these clam p-plates.) The clamp-plates are fixed on bars 30, revolubly mounted on-the table-plate, so that they may be lowered onto the material, or rather onto the cushion, or removed therefrom by the said bars being suitably turned. On these bars lever-arms 31 are mounted, which are connected, by means of links 38 and rods 32, with cross-bars 33, vdisplaceably mounted under the table-plate, Figs. 4 to 6. These cross-bars may be moved apart by means of a earn-piece 34, which is mounted on a shaft 35, vertically mounted in the machine frame and revolved from the drive-shaft 10 by means of bevel-gearing 36 in order to lay the clamp-plates on the cloth or the like for the purpose of clamping the same. Springs 37 serve for again lifting the clamp-plates off the cloth or the like in order to release it.

The working of the cloth or the like rubbing machine hereinbefore described is as follows: In Fig. 1 the machine is shown in a position in which the knives rest on the cloth or the like and the rubbing movement is commencing. The carriages 6 are then in their extreme left-hand position and the carriages 7 in their extreme right-hand position. On turning the shaft 10 in the directionA indicated the carriages 6 are moved to the right and the carriages 7 to the left, (see the arrows on the drawings,) the knives being thereby caused to rub the mate- Vrial from the edge to the middle-that is to say, from the outside inward. By this rubbing a uniform appearance and glaze is im- .parted to the materialwthat is to say, warpthreads which lie irregularly are laid evenly. When the carriages have reached the position shown in Fig. 12, they are moved by the action of the eccentric 11 into the position .shown in Fig. 13, from which they move into the position shown in Fig. 14 in order to again return to the position shown in Figs. 1 and 2, whereupon the rubbing again commences. The moment the knives assume the position shown in Fig. 12 the clamp-plates are lifted off the material, so that the latter may be moved forward by means of any known suitable mechanism. (In Figs. 7 to 10 the clamp-plates are shown in the position in which they clamp the cloth or other material during the rubbing, While Figs. 11 to 14 show the clamp-plates in the position in which they are lifted off the material.) The result of this forward shifting is that the cloth or other material is everywhere ru bbed and treated uniformly.

The machine shown may also be arranged in such a way as to rub the cloth or material from the middle to the edge. For this object the knives of the carriages 6 are displaced on the right hand longitudinal half and the knives 7 on the left-hand longitudinal half, so that now the material is rubbed from the middle to the edge.

The rubbing may be regulated by altering the pressure in the air-cushion.

I declare that what I claim isl. In a fabric polishing and finishing machine, in combination, an elastic or yielding bed, means to draw a fabric across said bed, means to hold the fabric thereon against lateral displacement, rubbing devices, and means to move the same at right angles to the warp to rub the fabric from its edges to its center.

2. The combination with an elastic or yielding bed, means to draw a fabric across said bed, clamping devices to clamp the edges of the fabric to the bed, and means to periodically move said devices to and from the bed; of rubbing devices, means to reciprocally move the rubbing devices at right angles to the warp of the fabric and rub the same from the opposite edges thereof to its center.

3. In a fabric polishing and finishing machine, the combination with an elastic or yielding bed, means to draw a fabric across said bed and means to hold the fabric thereon against lateral displacement; of rubbing devices, means to reciprocally move the same at right angles to the warp in contact with the fabric to rub the same from opposite edges to the center -thereof and to reverse the movement and simultaneously move the rubbing devices out of contact with the fabric and then again into contact therewith.

4. In a fabric polishing and finishing machine, the combination with an elastic or yielding bed, means to draw a fabric across said bed and means to hold the fabric thereon against lateral displacement; of carriages, rubbing devices secured to said carriages, means to reciprocally move the carriages to cause the rubbing-tools to act on the fabric from its edges to its center, and means to shift and adjust the rubbing-tools on their carriages to cause them to act on the fabric from its center to its edges.

5. In a fabric polishing and finishing machine, the combination with an elastic or yielding bed, means to draw a fabric across the same and means to hold the fabric against lateral displacement on the bed; of carriages, knives secured thereto and diverging toward opposite sides of the bed, means to reciprocally move said carriages at right angles to the warp of the fabric to cause the knives to rub the same from its edges to its center.
